Minor quibble... they had been Jefferson Starship for years at that point.
I haven't heard the song in many a moon, but here's what I remember:
intro:
Jane, you say it's all over for you and me, girl
There's a time for love and a time for lettin' it be, baby
Jane, you're playin' a game
Called hide-and-seek by its real name
Makin' believe that you just don't feel the same
(another verse but I don't remember it)
bridge:
Were all those nights we spent together
Only because you didn't know better
Jane, you're playin' a game
Bsus Bsus
Playin' a game, playin' a game
